Phyllobathelium is a genus of lichen-forming fungi in the family Strigulaceae.

[2][3] It comprises eight species of foliicolous (leaf-dwelling, crustose lichens.

The Swiss lichenologist Johannes Müller Argoviensis first proposed Phyllobathelium in 1883 as a section of the genus Bathelium.

[5] The main characteristic of the genus is the presence of black, amorphous to pulverulent (i.e., powdery and crumbly) structures on the upper part of the wall of the perithecium (fruiting bodies).

[6] As of August 2024[update], Species Fungorum (in the Catalogue of Life) accept eight species of Phyllobathelium:[2] Two species once placed in this genus have since been transferred to Swinscowia:[11] Phyllobathelium nudum Zahlbr.
